'Oppenheimer Blue' diamond sets new record, fetches $57 million

The “Oppenheimer Blue” diamond has sold for more than $57 million (56.8 million Swiss francs) including fees, crushing the previous record for the most expensive diamond ever sold at auction.

The 14.62-carats gem, auctioned at Christie's in Geneva Wednesday, was originally expected to fetch up to $46 million. The stone now belongs to a private collector after a 25-minute battle between bidders on three continents, the auction house said after the sale.

Only 10% of all blue diamonds discovered are larger than a carat, making the Oppenheimer Blue a highly prized freak of nature. It also has the highest color rating of "vivid."

The 12.03-carat "Blue Moon” diamond, sold by Sotheby's in November for $48.5 million, previously held the title of the priciest diamond sold at auction. The gem is now known as "The Blue Moon of Josephine.”
